[PATCH v2 2/4] Input: da9063 - Drop redundant prints in probe()

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

The memory allocation core code already prints error message in case of
OOM. So, drop additional print messages for OOM cases.

While at it, input_register_device() is already printing error messages on
failure. Drop the redundant print.
